Description

Die Erfindung betrifft eine landwirtschaftliche Feldspritze gemäß des Oberbegriffes des Patentanspruches 1.The invention relates to an agricultural field sprayer according to the preamble of claim 1.

Eine derartige landwirtschaftliche Feldspritze ist in beschrieben.Such agricultural sprayer is described in.

Derartige landwirtschaftliche Feldspritzen sind in der Praxis bekannt geworden, siehe z.B. EP-A-0 916 259 . Diese Feldspritzen weisen einen Flüssigkeitstank auf. In diesem Flüssigkeitstank ist zu dessen Innenreinigung eine zumindest eine Reinigungsdüse aufweisende Reinigungseinrichtung angeordnet. Die Reinigungseinrichtung ist an den von der motorisch angetriebenen Pumpe erzeugten unter Druck stehenden Flüssigkeitsstromkreis angeschlossen. Von diesem Flüssigkeitsstromkreis wird den Reinigungsdüsen zur Innenreinigung Flüssigkeit zugeführt. Damit die aus den Reinigungsdüsen austretende Flüssigkeitsmenge an die Flüssigkeitsausbringmenge der Feldspritze angepasst ist, müssen bei den bekannten Feldspritzen entsprechend in ihrer Größe angepasste Reinigungsdüsen von Hand in die Halterungen der Reinigungseinrichtung eingebaut werden. Hierdurch werden verschiedene auf den Flüssigkeitsmengenausstoß der Ausbringdüsen angepasste Innenreinigungsdüsen an den Halterungen der Reinigungsvorrichtung eingebaut. Die Anpassung ist erforderlich, damit bei dem Ausbringvorgang, wenn die Innenreinigung des Flüssigkeitstanks durchgeführt wird, bei aktiver Innenreinigung ein ausreichendes Druckniveau an den Reinigungsdüsen zur Verfügung steht, um so eine ausreichende Reinigungswirkung erzielt zu können.Such agricultural sprayers have become known in practice, see for example EP-A-0 916 259 , These field sprayers have a liquid tank. In this liquid tank, a cleaning device having at least one cleaning nozzle is arranged for its internal cleaning. The cleaning device is connected to the generated by the motor-driven pump pressurized fluid circuit. From this liquid circuit, the cleaning nozzles for internal cleaning fluid is supplied. In order for the amount of liquid emerging from the cleaning nozzles to be adapted to the liquid application rate of the field sprayer, in the known field sprayers, cleaning nozzles adapted to their size must be manually installed in the holders of the cleaning device. As a result, various adapted to the liquid quantity output of Ausbringdüsen internal cleaning nozzles are installed on the holders of the cleaning device. The adjustment is necessary so that in the dispensing process, when the internal cleaning of the liquid tank is performed, with active internal cleaning, a sufficient pressure level at the cleaning nozzles is available in order to achieve a sufficient cleaning effect.

Der Erfindung liegt die Aufgabe zu Grunde, in einfacher Weise es zu ermöglichen, dass auch relativ geringer Flüssigkeitsmengenzufuhr zu den Reinigungsdüsen eine möglichst gute Reinigungswirkung des Inneren eines Flüssigkeitsbehälters einer Feldspritze in einfacher Weise erzielt werden kann.The invention is based on the object to enable in a simple manner, that also relatively less Liquid quantity supply to the cleaning nozzles the best possible cleaning effect of the interior of a liquid container of a field sprayer can be achieved in a simple manner.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass Mittel vorhanden sind, über welche den Reinigungsdüsen bei dem Reinigungsvorgang des inneren Bereiches des Flüssigkeitstanks innerhalb definierter Zeitintervalle die Reinigungsflüssigkeit in zumindest zwei fortlaufend einander abwechselnden Abschnittsbereichen zuführbar ist.This object is achieved in that means are provided, via which the cleaning nozzles in the cleaning process of the inner region of the liquid tank within defined time intervals, the cleaning liquid in at least two continuously alternating section areas can be fed.

Infolge dieser Maßnahmen werden die Innenreinigungsdüsen in abwechselnder Weise so angesteuert, dass die aus den Innenreinigungsdüsen austretende Flüssigkeitsmenge trotz nur geringer Flüssigkeitsmenge immer mit einem ausreichend hohem Druck aus den Reinigungsdüsen austritt, so dass eine ausreichende Reinigung der Innenwände des Flüssigkeitstanks erreicht wird. Somit brauchen keine verschiedenen Düsen für unterschiedliche, auch geringen Ausbringmengen an der Innenreinigungsvorrichtung angebaut werden. Die Reinigung wird somit effizienter und mit weniger Wasser bei ausreichend hohem Druck möglich. Der Innenreinigungsvorgang lässt sich somit in einfacher Weise ohne Unterbrechung durchführen.As a result of these measures, the internal cleaning nozzles are driven in an alternating manner so that exiting from the internal cleaning nozzle liquid despite a small amount of liquid always exits with a sufficiently high pressure from the cleaning nozzles, so that a sufficient cleaning of the inner walls of the liquid tank is achieved. Thus, no different nozzles for different, even low application rates need to be attached to the internal cleaning device. The cleaning is thus more efficient and possible with less water at sufficiently high pressure. The interior cleaning process can thus be carried out in a simple manner without interruption.

Um bei nur geringer zur Verfügung stehender Flüssigkeitsmenge bei der Durchführung der Innenreinigung bei einen ausreichend hohen Reinigungsdruck zu erreichen, ist vorgesehen, dass die Reinigungsdüsen zum fortlaufenden intervallweisen Ausstoßen von Reingungsflüssigkeit einzeln nacheinander in definierten Zeitabschnitten mittels geeigneter Mittel ansteuerbar sind.In order to achieve a sufficiently high cleaning pressure with only a small amount of liquid available when carrying out the internal cleaning, it is provided that the cleaning nozzles for continuous interval ejection of cleaning liquid can be controlled one after the other in defined time intervals by suitable means.

Um bei nur geringer zur Verfügung stehender Flüssigkeitsmenge bei der Durchführung der Innenreinigung bei einen ausreichend hohen Reinigungsdruck zu erreichen, ist in einer weiteren Ausgestaltung vorgesehen, dass die Reinigungsdüsen zum fortlaufenden intervallweisen Ausstoßen von Reinigungsflüssigkeit gruppenweise zusammengefasst sind und die einzelnen gruppenweise zusammengefassten Reinigungsdüsen nacheinander in definierten Zeitabschnitten mittels geeigneter Mittel ansteuerbar sind.In case of only a small amount of liquid available when performing the internal cleaning at a sufficient To achieve high cleaning pressure is provided in a further embodiment that the cleaning nozzles for continuous interval ejection of cleaning liquid are summarized in groups and the individual groups summarized cleaning nozzles are sequentially controlled in defined time intervals by suitable means.

Um in einfacher Weise zur Erreichung des ausreichend hohen Reinigungsdruckes die verschiedenen Reinigungsdüsen anzusteuern, ist vorgesehen, dass die Mittel zum intervallweisen Ausbringen der Reinigungsflüssigkeit durch die Reinigungsdüsen über eine elektronische Steuer- und/oder Regeleinrichtung ansteuerbare Ventilelemente, die der Reinigungseinrichtung und/oder den Reinigungsdüsen zugeordnet sind, sind.In order to control the various cleaning nozzles in a simple manner to achieve the sufficiently high cleaning pressure, it is provided that the means for interval application of the cleaning liquid through the cleaning nozzles via an electronic control and / or regulating device controllable valve elements associated with the cleaning device and / or the cleaning nozzles are, are.
